1. How does Cygwin detect whether something is a MSFT NFSv3, or not?
Cygwin /bin/mount lists the CITI NFSv4.1 as 'nfs', so there *IS*
something which detects that?
2. Are Cygwin soft link handing depend on MSFT NFSv3 or not, i.e. does
the Cygwin soft link code behave differently for MSFT NFSv3 file
systems?
3. Does Cygwin implement the pathconf() api?

Thanks,
